Amazon’s Appstore for Android is not exclusively available for the Kindle Fire, but at this point that is the device that matters. The relatively new media tablet already holds the majority share of the Android tablet market and has proven more or less untouchable by comparably priced hardware competition so far. The secret, if it can really be said to be one, is in the content. Amazon has just about anything one might want to consume through the Fire ready to go at a moment’s notice with the push of a button. Nobody else can come close for the price.

When some major shortcoming is addressed in the design of their ecosystem, it is therefore worth taking note of. Like the recent announcement that developers now having access to the option of in-app purchasing, completely changing the potential for ongoing revenue from Kindle Fire owners. This is a long-time staple of iOS app market that is well overdue here.

Until this point, Amazon affiliated app creators have earned a reported $0.89 for every $1.00 they earn selling the same offering through the iTunes App Store. That is despite the lack of ongoing microtransactions supported by Amazon. For comparison, the same app being sold through Google Play will earn an average of $0.23 for every dollar its creator catches via iTunes.

Opening up more possibilities for developers to make money through Android will put Amazon in a better position to build the best app selection available. Currently, in sheer numbers, they are lagging behind both Apple and Google significantly. By allowing options that don’t involve advertisements or unpopular third party tools, Amazon is making the Kindle Fire an even more attractive option.

This does open up some potential drama for Kindle Fire owners, of course. The biggest draw of Amazon’s 1-Click purchasing system is that it is so easy you almost don’t notice you’re spending money. Combine this with apps that are designed to offer quick and easy purchases and you may well have a recipe for personal financial disaster.

Many will recall an incident in the earlier days of the iPad when an eight year old girl made news buying Smurfberries to speed up her in-app play. The bad publicity from this and similar events is what brought about the iPad’s detailed array of Parental Controls.

Amazon hopes to avoid similar efforts by having fewer loopholes in their existing restrictions. Kindle Fire users have the ability to block in-app purchasing entirely, password protect the process using their Amazon account password, or create a PIN to unlock purchasing. Between these choices, there should be little room for complaint about accidental shopping unless users simply don’t know how to access the controls.

For reference, you can manipulate Kindle Fire In-App Purchasing settings by going to the Apps tab from the Home screen, clicking on the Store, and opening the Settings menu. Since all purchasing appears to be routed through this store app, it makes sense to find these settings here.
